The NeoAir VR weighs just 26.5g, and it measures 37.6mm in diameter. It
has a USB Type-C connector, and you can plug it directly into an Android
smartphone that has the new reversible port. If you go this route,
you're able to broadcast your 360-degree videos live on Facebook,
Twitter, and YouTube. The phone needs to have at least 2GB of RAM
though, as well as USB OTG support.
